CUSHION-HEELI To a-ZZ 'whom it may concern: i i

Be it known that I, ALFRED BUcoLo, a subject of the King of Italy,residing at Washington, in the District of Columbia, have invented newand useful Improvements in Cushion-Heels, of which the following is aspecification; p

The object of my present invention is the provision of a cushion heelpossessed of great suction capacity in addition to other practicaladvantages, and this notwithstanding the fact that the heel issusceptible of cheap production.

To the attainment of the foregoing, the invention consists in theimprovement as hereinafter described and definitely claimed.

In the accompanying drawings, forming part hereof z Figure 1 is aninverted plan view of a cushion heel constructed in accordance with myinvention.

Fig. 2 is a top plan view of the heel.

Fig. 3 is a longitudinal vertical section showing the cushion heel asproperly attached to the leather heel lifts of a Shoe.

Fig. 4 is a transverse section of the cush ion heel, taken in the planeindicated by the line 4-4 of Fig. l.

Similar numerals of reference designate corresponding parts in all ofthe views of the drawings.

In common with cushion heels at present =in general use my novel cushionheel 1 is for-med in one piece of vulcanized rubber or other appropriateresilient material compatible with its purpose.

In its underside my novel heel 1 is provided with a vacuum chanber 2which is preferably, though not necessarly, of stepped formation and isclosed at its top by the wall 3, this provision being advantageousinasmuch as the wall 3 is enabled to prevent water from reaching thelifts 4 of the shoe heel and deteriorating said lifts. The heel 1 isalso provided with nail holes 5 and with small suction chambers 6 whichreach from the said nail holes 5 to the under surface of the heel. Atits underside the heel 1 is provided with integral projections 7 andwith an auXiliary suction chamber 8 the said chamber 8 being formed bythe curvilinear rib 9 and the transverse rib 10. It will be understoodby comparison of Figs. l and 2 that the projectons 7 are arrangedslightly in front of the transverse median line of the heel, and thesuction Specificati'on of Letters Patent.

chamber 8 is arranged at the rear of the heel, and byparticular"referenceto Fig. 3 it will be noted that the. the ribs 9 and10 are of squarely on the surface.

It will also be understood that after afew PEATENIT OFFICE,

projections, 7 and i a `,common depth. From this it follows thatincident to the use prevent slipping of the weeks of wear, theprojections 7 and the ribs t 9 and l0 willbe worn away so that' thesurface ll of theheel will pavement or the like. At this latter time thesuction chamber 2 will come into play and will effectively preventslipping of the heel on a wet pavement or other surface.

y virtue of the provision of the projections 7 and the ribs 9 and 10 theheel is adapted to be worn for a material time without any wear whateverof the body of the maj or portion of the heel, and from this it fol*lows that the projections 7 and the ribs 9 and 10 are calculated toprolong the usefulness of the heel considered as a unit. At its upperside the heel 1 is provided with a U-shaped marginal fiange 12, theouter and inner corners of which are rounded as indicated by 13 and 14,respectively, F ig. 4, so that when the heel l is applied to a lift 4and nails 15 are driven through the nail holes 5 and into the lifts 4,the portion of the heel l within the flange 12 will be carried to andsnugly held against the lowermost lift 4, and at the same time the edgeportion of the heel 1 will be snugly crowded against the lowermost lift,with the result that a neat finish will be produced and at the same timewater will be prevented from entering between the cushion heel 1 and thelowermost lift 4. This will be better understood when it is stated thatwere the corners 13 and 14 sharp right angle corners, the compression ofthe heel 1 incident to its application to the heel lifts 4 would beattended by spreading of the fiange 12 so that the uppermost portion ofthe heel 1 would be of greater area than the portion of the heel 1 belowsaid uppermost portion and in consequence the applied heel would not beas neat and finished in appearance as the heel characterzed by therounded corners 13 and 14. The edges of the heel l are preferably shapedas shown so that the be presented to a' area of the underside of thecushion heel l t heeli lifts 4 with the result that the` cushion Ifeelwill be possessed of a large exposed surace. i v Having described myinvention, what I claim and desire to secure by Letters Pat-` psed inrear. of the first-named slotion' d .auxiliary suction 'cham chamber;the sai ber being formed by pendent curvilinear and cross rib's, and thesaid projections and ribs being of a common height. i

2. As a new article' of manufa'oture, a; cushionheel having in itsunderside a suction chaiber closed at its top, and also hay ing pendentprojectons spaced apart in front of the transverse medianline of the i warticle of manufacture, a

heel, and an auxiliary sucton chamber disposed in rear of thefirst-named 'suotion chamber; the said anxiliary suction ohamber beingformed by pendent curvlinear and cross ribs, and the said projectons andribs being of a common height, and the said heel also having at itsupper side a U-shaped -fiangethe outer and inner cornersof which arerounded. i i

3. A cushon heel having'at the underside oi: its real' portion a,su'ction charnbe'r `and alsohaving at its underside and spaced apat and'in front of the sucton chamber pendent proj ections; the said suctionCham ber being defined by a curyilinear rib and a connecting rib and thesaid ribs andthe said projectionsbeing'ofa commonheight, whereby the,said suction 'chamber is adapted to serve until the rbs and pendentprojections are worn away.

In testimony whereof I afliX my signature.
